Wagler WCPC66125.1 Billet Water Pump3488810.00
Upgrade to the Wagler WCPC66125.1 Billet Water Pump and eliminate the dreaded water pump issues on your 2006-2016 GM 6.6L Duramax. The factory water pump impeller often separates from the shaft, resulting overheating conditions. The aftermarket has tried to solve this issue by pinning or welding the impeller to the shaft. However, these methods still fail. The Wagler WCPC66125.1 Billet Water Pump is a complete solution to end this frustration that many Duramax owners have experienced. The Wagler Billet Water Pump is great for any application whether it's a race truck, or a stock daily driver. This water pump features an all billet construction with ceramic seals and roller bearings. In addition, the drive gear shaft made from hardened tool steel is reverse threaded.

Eliminate the hassle of servicing the cooling system in your 2006-2019 GM 6.6L Duramax with the XDP Duramax Radiator Drain Pipe XD328. Draining the cooling system in your truck requires removal of the lower radiator hose. Once that hose is removed, you'll find yourself scrambling trying to contain the mess of over 4 gallons of coolant. While some use buckets, kiddie pools, and many other methods, none solve the real issue of trying to eliminate the mess and contain the coolant so it can be re-used or properly disposed of without splashing all over the floor of your shop, garage, or driveway. The XD328 Duramax Radiator Drain Pipe helps you keep things clean and controlled during routine maintenance. With the included ball valve, you can drain your cooling system with just the turn of a lever. Built from CNC machined billet aluminum, the XD328 installs in-line with one easy cut through the lower factory radiator hose. Simply cut the hose, slide the XDP Radiator Drain Pipe in place, and tighten down the included T-bolt clamps to complete the installation. Each drain valve comes ready to install and is anodized black for aesthetics and corrosion resistance. Features:Black Anodized FinishSimply Cut Existing Hose and Install CNC Machined Billet Aluminum ConstructionAllows Easy Controllable Draining Of Cooling System

Don't just replace the failed radiator in your 2011-2016 GM 6.6L Duramax with a stock replacement, upgrade it with the XDP X-TRA Cool Direct-Fit Replacement Radiator XD292. Designed for a simple bolt-on installation, XDP's X-TRA Fit Radiators look like a factory replacement, but are upgraded to be stronger and better than the factory unit. Manufactured with several techniques borrowed from the HD and Semi truck industry, the X-TRA Cool Radiators are built to give you a long-lasting direct-fit option to protect your engine and cooling system. High Efficiency CoreThe X-TRA Cool Radiator is built with a high-efficiency core that has more fins per inch, and heavy-duty tubes to maximize cooling potential. Internal ReinforcementsManufactured using special aluminum brazing techniques, the X-TRA Cool Radiator features internally reinforced end tubes that have additional strength at the outside corners where the core is most vulnerable.Gasket DesignUsing a proprietary rubber gasket to allow for expansion, contraction, and flex is one more reason the X-TRA Cool Radiators are built to last. The gasket is a common failure point in many OE radiator designs. Revised End Tanks For added strength and durability the X-TRA Cool Radiators feature revised end tanks. With reinforcement ribs added to weak points, the plastic mix includes a fiber reinforcement that is added during construction to increase longevity and help eliminate another failure point.Upgraded Mounting PointsTo make sure the X-TRA Cool Radiator is securely mounted in the same location as your stock radiator, the integrated mounting points have been strengthened to add durability. Tank Attachment To join the tanks to the core on the X-TRA Cool Radiators, XDP uses a heavy gauge steel crimp strip. Unlike the aluminum that the factory design uses, the steel crimp strip eliminates tank and core separation that many experience with the factory radiator.
